Periodically (e.g. annually or semiannually), the Office of the Chief Financial Officer (OCFO) prepares and sends a listing of UDOs, by office, that meet pre-defined criteria for de-obligation (e.g. period of performance has expired) to each office within USITC. Each office should then provide a timely response (e.g. within 30 days) notating which UDOs are ready for de-obligation and an explanation beside those that are not ready for de-obligation. Upon receipt of the responses, the CFO will then initiate the de-obligation process for those identified as ready for de-obligation.
